PIGK.

To all whom t may coacem:

Be it known that I, EDGAR H. WATT, a citizen of the United States, residing at West Newton, in the county of 'VVestmoreland and State of Pennsylvania, have 1nvented new and useful Improvements in Picks, of which the following is a specification.

This invention relates to picks, and more particularly to a pick provided with a detachable point. t

@ne of the main objects of the invention is to provide a pick ofvsimple construction and operation in which the point may be readily applied or detached, as desired. A further object is to provide simple and efiiclent means for effectively bracing the point against strains encountered in use of the pick. Further ob-jects will appear from the detailed description.

In the drawings j Figure 1 is a fragmentary top plan view of a pick head constructed in accordance with my invention;

Figure 2 is a side view; i

Figure 3 is a side view partly broken away.

The pick head 1 is of usual construction being provided with an eye 2 for reception of the handle from the opposite sides of which project arms 3. Each arm is provided at its outer end with a tongue 4 which fits snugly between projections 5 at the inner end of a point'. Each of these projections is provided with an inclined inner face 7 from the inner end of which extends a fiat projection 8 provided at its central point with an inwardly tapering linger 9. Members 5 fit snugly into corresponding slots exe tending transversely of arm 3, and ngers 9 it tightly into corresponding recesses provided in the arm. Tongue 4 is provided at its outer end with an integral pin 10 which its into a corresponding recess provided in the inner end of point 6. Al tapered wedge l1 is driven through aligned openings provided in members 5 and tongue 4, and is secured in position by a set screw 12.

The pin 10 and fingers 9 co-operate to effectively brace the point 6 against strains transversely of arm 3and tongue 4 cooperates with members 5 of the point and with elements 5a of arm 3, to eifectively brace the point against strains vertically of arm 3. In this manner the point is effectively secured to the arm of the head and is Specification of Letters Patent. Patented June 13 1922.

locked against all looseness or play while being effectively braced so as to withstand the strains to which it is subjected in use. By removing set screw 12 and wedge 11 the point may be readily removed so as to be replaced or repaired, as will be understood.

What I claim is In a pick, a head including an arm, a point provided at one end with spaced members having fiat elements extending from their inner ends, said elements being provided at their inner ends with inwardly projecting fingers, said arm being provided at lts outer .end with a tongue fitting snugly between said spaced members and with slots and recesses receiving the fiat elements and fingers of the point, and means for detachably securing the point to the arm.

2. In a pick, a head including an arm provided at its outer end with spaced elements and slots extending transversely of the arm, said arm being further provided with recesse's communicating with .said slots and with a tongue projecting outwardly of the arm between said elements, a point provided at its inner end with spaced members receiving between them said tongue, said members contacting with the spaced elements of the arm and being provided with elements iitting snugly into said slots and recesses, and means for detachably securing said point at the arm.

3. In a pick, a head including an arm provided at its outer end with a central outwardly projecting tongue and with outwardly projecting elements above and below the tongue, the outer ends of said elements being inclined and the head being further provided with transverse slots at the inner end of the tongue and with recesses communicating with said slots, said tongue being provided with a pin at its outer end; a point provided with spaced members snugly re-` ceiving between them the tongue and having their inner ends inclined similarly to and in contact with the outer ends of said elements of the arm, said members being provided at their inner ends with flattened members and fingers fitting snugly into the slots and recesses of the arm, the point being further provided with a recess snugly receiving said pin; and means for detachably securing the point t0 the arm.

In testimony whereof I aiiX my signature.
